john-okeefe 85964ec932 fix(api): enforce user isolation on saved filters delete operation
Fix critical security issue where admin users could delete other users'
saved filters due to incorrect error handling in DELETE query.

Database Schema Changes:
- Change DeleteSavedFilter from :exec to :one (queries.sql:1747-1750)
- Add RETURNING * to return deleted row for proper error detection
- Regenerate querier.go and queries.sql.go with updated signature

Service Layer (internal/services/filters.go):
- Update DeleteSavedFilter to capture returned row (using _ to discard)
- Properly propagate pgx.ErrNoRows when no rows are deleted
- Error wrapping preserves original error for handler detection

Handler Layer (internal/handlers/filters.go):
- Add errors.Is() check for pgx.ErrNoRows (line 148)
- Return 404 Not Found when filter doesn't exist or belongs to different user
- Return 500 Internal Server Error for other database errors
- Add "errors" import (line 8)

Security Fix Details:
Before: Admin could delete user's filter → 204 No Content (SUCCESS)
After:  Admin tries to delete user's filter → 404 Not Found (DENIED)

The DELETE query uses WHERE id = @id AND user_id = @user_id, which matches
0 rows when attempting to delete another user's filter. The old :exec query
didn't return row count, so 0 affected rows looked like success. The new :one
query with RETURNING * returns pgx.ErrNoRows when no rows match, allowing
the handler to return proper 404 error.

Test Impact:
- TestSavedFilters/User_cannot_access_another_user's_filter now passes
- All 6 integration tests pass with proper user isolation enforcement

Pattern Consistency:
- Matches DeleteLibraryFolder pattern (line 99 in queries.sql)
- Uses same error handling as media handlers (errors.Is + pgx.ErrNoRows)
- Follows user-scoping pattern used throughout codebase
